Abstract (en)

A compound of the formula (IA) or (IB) <CHEM> wherein G1, G2, G3 and G4 are independently of one another C1-C18alkyl or C5-C12cycloalkyl or the radicals G1 and G2 and the radicals G3 and G4 form independently of one another, together with the carbon atom they are attached to, C5-C12cycloalkyl; R is hydrogen C1-C18alkyl, C1-C18hydroxyalkyl, C2-C18alkenyl, C5-C12cycloalkyl, C7-C12phenylalkyl unsubstituted or substituted on the phenyl radical by C1-C4alkyl and/or C1-C4alkoxy; or C1-C18alkanoyl; R* is hydrogen, C1-C18alkyl, oxyl, -OH, -CH2CN, C3-C6alkenyl, C3-C8alkynyl, C7-C12phenylalkyl unsubstituted or substituted on the phenyl radical by C1-C4alkyl and/or C1-C4alkoxy; C1-C8acyl, C1-C18alkoxy, C1-C18hydroxyalkoxy, C2-C18alkenyloxy, C5-C12cycloalkoxy, C7-C12phenylalkoxy unsubstituted or substituted on the phenyl radical by C1-C4alkyl and/or C1-C4alkoxy; C1-C18alkanoyloxy, (C1-C18alkoxy)carbonyl, glycidyl or a group -CH2CH(OH)(G) with G being hydrogen, methyl or phenyl; n is 1, 2, 3 or 4; n* is 1, 2 or 3; X is an organic radical of a valency equal to n; and X* is a triazinic radical with a valency equal to n*; with the proviso that when n is 1, R is methyl, ethyl, propyl, C1-C18hydroxyalkyl, C2-C18alkenyl, C5-C12cycloalkyl or C1-C18alkanoyl. The compounds described above are useful for stabilizing an organic material against degradation induced by light, heat or oxidation.
